The two shafts $$AB$$ and $$BC$$, of equal length and diameters $$d$$ and $$2d$$, are made of the same material. They are joined at $$B$$ through a shaft coupling, while the ends $$A$$ and $$C$$ are built-in (cantilevered). A twisting moment $$T$$ is applied to the coupling. If $${T_A}$$ and $${T_C}$$ represent the twisting moments at the ends $$A$$ and $$C,$$ respectively, then
A
$${T_c} = {T_A}$$
B
$${T_c} = 8{T_A}$$
C
$${T_c} = 16{T_A}$$
D
$${T_A} = 16{T_C}$$

A torque of $$10$$ $$N-m$$ is transmitted through a stepped shaft as shown in figure. The torsional stiffnesses of individual sections of lengths $$MN, NO$$ and $$OP$$ are $$20$$ $$N-m/rad,$$ $$30$$ $$N-m/rad$$ and $$60$$ $$N-m/rad$$ respectively. The angular deflection between the ends $$M$$ and $$P$$ of the shaft is
A
$$0.5$$ $$rad$$
B
$$1.0$$ $$rad$$
C
$$5.0$$ $$rad$$
D
$$10.0$$ $$rad$$
